As a straight male the thought of a woman pleasuring herself to my photos would be an enormous turn on even though I know given the way females are wired, even on a website such as this (maybe even especially here), there is no way in hell it would happen.
Therefore I realize the reality that anything I have posted here is being viewed 99% of the time by other males, which may or may not include being used for wank material. However there is also the reality that I could care less and more power to them as I can't control (nor would I), what gender or orientation views them. Even though the one using them may not be my cup of tea, I admit I'd still feel somewhat flattered that in a sea of wang, mine somehow stood out, especially given I've never considered it anything special. As long as there is the understanding that by admitting such to me is not going to change my current preferences, then have at it.
Now of course if one is jerking off to the pictures of my wife, we are back into arousal territory and such admissions are always welcome.
